looks like a repaint. has the IROC-Z decals, but not the stripes. i see one other thing. In 1988 regular Z28's were dropped. All Z's were IROCs through 1990. Now that car has an IROC-Z badge on the bumper, but incorrect Z28 badges on the ground effects. Those should say IROC-Z as well. Might be a real IROC, i'd just look into that.
